JOI-IN N. JOHNSON, OF HOUSTON, TEXAS, ASSIGNOR TO MAI-ION E. LAYNE, OF HOUSTON, TEXAS.

WIRE-WINDING MACHINE.

Application filed February 18, 1908.

To all whom it may concern.

Be it known that I, JOHN N. JOHNSON, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Improvement in a VVirelVinding Machine, of which the following is a specification.

This invention relates to machines for winding wire and particularly to a machine for coiling wire in the construction of well screens and the like.

The objects of the invention are the provision of means for forming notches in spiral or helical order or producing a spiral or helical groove in a supporting body; means for seating or coiling a wire in said notches or groove; means whereby the seat or groove is formed in advance of the coiling or seating of the wire; means for supporting the body on which the wire is wound, whereby a uniform dept-h of groove or seats will be had; means for regulating the depth to which the seats or grooves are out; means for placing the wire under tension and varying such tension; and means whereby the supporting frame is centered about the work.

Finally the object of the invention is to provide means of the character described that will be strong, durable, efiicient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out of working order.

With the above and other objects in view, the invention has relation to certain novel features of construction and Operation, an example of which is described in this specification and illustrated in the accompanying drawings, wherein:

Figure 1. is a perspective view of the machine showing the wire partially coiled about a piece of pipe, Fig. 2. is a longitudinal sectional view of the same, Fig. 3. is a plan view, Fig. 4:. is a vertical sectional view on the line 4-4 of Fig. 2, and Fig. 5. is a vertical sectional view on the line 55 of Fig. 2.

In the drawings, the letter A, designates a carriage adapted to be mounted in the slide-way of a lathe bed and to travel therealong. The carriage is provided at each end with a bearing A in which the outwardly projecting trunnions B' of a frame C are mounted. On one of the trunnions, a

coiled spring B is confined, whereby the frame is held .in position against a collar B on the other trunnion, which collar abuts the carriage. The frame is thus pivotally mounted and may be removed when desired.

A pair of parallel arched side bars C spaced apart, extend forwardly from the rear portion of the frame, one of said bars having adjacent its inner end, a bearing C in which a trunnion D having a wrench receiving end is mounted. The trunnion D is fixed at its inner end to the central portion of a tension bar D lying against the inner side of the said side bar and carrying a grooved roller D on its rear end and a smooth roller D on its forward end. The roll-er D has its groove, V-shaped in cross section so as to receive a corresponding shaped wire E and guide it with its broad side up and thus present this broad and flat side to the smooth periphery of the roller D It is obvious that by turning the trunnion D, the tension bar is swung and the rollers positioned so as to give the desired tension to the wire and in this way the tension may be varied and regulated. When the rollers have been properly positioned, the parts are fastened in place by a set screw D threaded through the bearing and impinging the trunnion.

The wire E is fed from a suitable support into the rear of the machine, passing in straight alinement to the roller D over the same and under the roller D then upward and over a grooved roller F loosely confined on a stub shaft F secured in one of the side bars on the arched portion thereof, then over a grooved roller G mounted on a similar stub shaft G and finally down around the body about which the wire is being coiled or wound, the alinement being retained throughout the passage of the wire through the machine to the point where it enters into engagement with the body.

Opposed bearings H and H are provided in the side bars at the arched portion. The bearing H receives a sleeve K which extends inward a short distance from the side bar and is locked in position by a set screw K while an eccentric bushing L is mounted in the bearing H and locked by a set screw L This bushing extends inward and is secured on a horizontal shaft I which also passes through the sleeve K. The shaft I projects beyond the outer end of the bushing and has wrench receiving end by which it and the bushing may be turned after the set screw L has been loosened. A gage roller L is loosely mounted on the bushing and extends within a short distance of the sleeve K.

On the shaft I, a revolving cutter wheel M is loosely confined between the roller L and the sleeve K. This cutter wheel has a diameter greater than that of the roller so as to permit the roller to bear on the previously wound portion of the body while the cutter wheel is performing its function. It will be seen that by adjusting the bushing, the roller will be raised and lowered, the projection of the cutter wheel below the roller varied, and the depth of the cut gaged or regulated.

It is evident that some means for holding the body on which the wire is coiled or wound, up to the cutter wheel, must be provided. It is also apparent that owing to the varying conditions of the body, such as longitudinal curvature, unevenness of periphery, or distorted cross sectional shape, means for allowing the body to revolve in its natural course must be included. To meet these and other conditions, a standard N is pivotally secured to each side bar C These standards are provided with a series of openings N in which a bolt N is adapted to be secured.

A frame 0 is disposed under the frame C and in substantial parallel relation thereto. This frame O comprises parallel side bars 0 pivotally mounted at their forward ends on the bolt N and impinging the inner sides of the standards. The frame 0 supports between its side bars 0 a pair of broad face idle rollers P, separated a suflicient distance to properly support in position, the body on which the wire is wound. These rollers are also disposed so as to position the body with the cutter wheel substantially over the longitudinal axis of the body. In this way the body is held in proper relation to the cutter wheel.

It is understood that the body which may be several feet in length is chucked in the lathe and thus revolved. To accommodate various diameters of bodies, the bolt N is shifted in the openings N and the frame 0 raised or lowered as the case may be. The wire being fed to the body as previously described is wound thereon as the body is revolved.

At their rear ends the side bars of the frame 0 are connected by a cross rod to which the lower end of an extension spring R is pivotally connected. At its upper end the spring is connected to the lower end of a screw threaded rod Q. This rod at its lower end is loosely confined in an arm C extending from the lower edge of one of the side I bars C to which it is rigidly attached. A

lever R fulcruinect on the yoke ppi'tion of i the frame 0 extends to the iear of the machine and is bifurcated at its forward end so as to straddle the rod Q under a nut adjustable thereon. At its rear end the lever is held down by suitable means (not shown) and the frame 0 yieldably supported. It is apparent that the nut on the rod Q should be adjusted just the same as the bolt N to accommodate different diameters of bodies. The function of the lever, rod and spring is to hold the body in yieldable engagement with the cutter wheel and thus should there be a depression in the body this mechanism will force the body up to the cutter wheel and preserve the uniformity of the cut; and likewise should there be a bulge on the body the mechanism will permit the body to move away from the cutter wheel and preserve the uniformity of the cut. As a matter of fact the frames C and O, the standards N, the spring R and the rod Q form substantially a general frame surrounding or encircling the body. The lever, rod and spring substantially form means for centering this geni eral frame upon the body. It is further to be noted that the standards N being pivoted to the frame C and having pivotal connection with the frame 0 and the latter being pivotally supported at its rear end, the said frame 0 may have a limited longitudinal moven'ient, or that is a movement at right angles to the longitudinal axis of the body thus permitting the winding of a body which has a slight longitudinal curvature.

It is to be understood that the carriage A is connected to the feed mechanism (not shown) of the lathe and thus carried along the slide-way or bed of the lathe, the distance between the convolutions of the wire wound on the body depending upon the speed at which the carriage is moved along the lathe bed. It is obvious that the roller L bearing on the wound portion of the body will hold the cutter wheel M to a uniform depth of cut and that by adjusting the bushing L the cutting wheel is adjusted toward and from the axis of the body 011 which the wire is wound. lVhile I have shown a body provided with external ribs it is to be understood that the machine may be used in connection with bodies having a smooth surface or frames in the form of cylindrical bodies.

It is to be noted that in actual practice the body to be wound with wire is supported by the lathe and the general frame which surrounds the body while in a sense supporting the body is really a device for holding the cutter in operative relation to the body and permitting the cutter to follow the irregularities of the periphery of the body. This frame of course has other functions as hereinbefore explained. It also might be proper to state that the cutter wheel lVI has a V- shaped cutting edge and the wire employed 18 substantially V-shaped in cross section, but of course other shapes may be employed. Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is I 1.
